DESCRIPTION:Speakers: Liesl Burger (National Laser Centre)\nIt is well und
 erstood that the fundamental mode of a cavity may be selected by suitable 
 choice of intra-cavity amplitude or phase elements.  If one wishes to dyna
 mically control the mode\, for example\, to manage thermal aberrations\, t
 hen intra-cavity elements that are controllable are required.  Two such el
 ements are adaptive mirrors and spatial light modulators (SLMs).  In this 
 poster we present early results on the intra-cavity use of SLMs\, and high
 light some expected and unexpected problems.  We then compare our results 
 to our first attempts at the use of an intra-cavity adaptive mirror.\n\nht
